Carbon Steel and Mild Steel Metal Casting Resources

Carbon steel is comprised of iron and carbon, and is the most common category of steel, making up approximately 85% of all steel production in the US. The carbon content of the product is in the 02% range and gives the metal carbon-like properties due to the influence of the carbon on the microstructure.

A Brief History of the American Steel Industry National

Steel supply was crucial for rapid expansion of cities and urban infrastructure. Railroads, bridges, factories, buildings, and eventually, in the 20th century, steel was used to make appliances and automobiles. It was at this time that the US steel industry began using the open-hearth furnace, then, the basic oxygen steelmaking process.

1A Manufacturing Process for Iron and Steel

The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas (CO) generated by the oxidation of the carbon (C) in coke.

Difference Between Iron and Steel Difference Between

Difference Between Iron and Steel. When iron ore is processed with coke in a blast furnace, pig iron is obtained. When this pig iron is further processed to reduce the carbon percentage, in various furnaces, steel is obtained. Now, steel can be further processed to obtain various types of alloys. Elements like silicon, manganese and chromium are added for making alloys.
